top speed

Just trying to sort out kind of a weird issue I've been having with an XP I've been working on over the season. I just put a new motor (165PSI in both cylinders) in it with freshly cleaned and rebuilt carbs. Mikuni kit, popoff on both carbs right at 29PSI. LS needles at 1-1/4, HS at 1/4...

My 2017 GTR 230 lost 20mph off the top speed from last year. I purchased the 2017 GTR 230 used last year. Ran great in the Summer and hit 65mph before I put it on the trailer last Fall. I had the local dealer winterize it. I removed and stored the battery inside the house (I don't like to...

I have a 1999 Seadoo Sportster 1800 with twin 717's. I've had other Seadoo's before, but this boat is new to me this year, and I'm trying to make sure it's running like it should. What are other's getting for top speed out of these? I had it out last night and hit 42mph by myself on a glassy...

Last post for today. There was another thread that mentioned expected top speed and associated RPM. The other day I took a picture when running near full throttle simply because it felt so good to have nearly 100% of the speed designed into the boat while the RPM / motors were in Sync...

Hi, I recently got a 2008 Seadoo RXP-X for my graduation gift from my father and have a few questions about it.. I've taken it out 4 times already the past 2 weeks and this thing is a beast!! So last time I went out I wanted to see the top speed of it because I heard that the Speedometer...

i am new to jetskiing, and after a season with my machine, im eager to increase my top speed. my top speed now is about 63mph, and i want to see how much higher i can go. thanks.

just wondering if that is a good top speed for that ski or not?

Hi, I am new to this forum but have been reading threads about the seadoo challenger 180. I just bought my seadoo challenger this year and have had it out 3 times this summer. I was told the supercharger was replaced once already. The boat seems to run fine, RPM goes up to 8000+ rpm when at...

Hey i was just wondering what other people with a 2000 SeaDoo GTX Milenium Edition with a stock engine got for their top speed. My speedometer showed 68 on a speed run but later i did a GPS recording and it showed 51 as the top speed and i couldn't believe that the speedometer was so far off.
